Fish and Aquatic Life
This high-quality trout stream supports reproducing populations of numerous brook, and migratory brown and rainbow trout. Springs provide the majority of the stream's flow, but poor quality drainage from a shrub swamp at its headwaters in Bayfield County contributes to its flow. This stream is considered an outstanding resource water as part of the ABrule System@ identified in NR102. It does, however, originate in Bayfield County, and the code as written lists only streams that originate in Douglas County. The Bureau of Watershed Management interprets the intent of the ruling: and considers the entire length of the stream an outstanding resource water.
During survey work conducted as part of the coastal wetlands evaluation, two rare species were found and overall taxa richness was moderate (5-24 species) (Epstein 1997). The survey noted that streambank erosion and cropland, as well as silt, may pose a threat to the stream.

Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available.
Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2016 . See also 'monitoring' and 'projects'.
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.

Rocky Run is located in the Bois Brule River watershed which is 199.64 mi². Land use in the watershed is primarily forest (66%), grassland (13%) and a mix of wetland (11%) and other uses (9%). This watershed has 220.94 stream miles, 3,539.94 lake acres and 18,373.66 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Not Available for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
